Embodiment Construction

[0013] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

[0014] Aiming at the shortcomings of the communication between the charger and the battery in the prior art, the present invention proposes a method that can identify more battery information, so that the output voltage and current of the charger when charging the rechargeable battery are more in line with the current state of the battery. requirements to avoid damage to the rechargeable battery.

[0015] In the present invention, an information library is pre-stored in the main control circuit of the charger, and the information library includes pulse signal frequency information, battery model and battery status information paired with the frequency information.

[0016] Therefore, there are three conducting lines between the charger and th...

Abstract

The invention provides an identification method of a charger for a battery. An information base is previously stored in the main control circuit of the charger. The method comprises the steps: the control circuit arranged in the battery collects the model of the battery and state information, converts the information into a pulse signal of a characteristic frequency, and sends the pulse signal tothe main control circuit of the charger through a circuit switched on when the charger is used for charging the battery; and the main control circuit of the charger receives the pulse signal and identifies the model and battery state information of the battery embedded in the charger referring to the information base according to the frequency of the pulse signal. The invention defines different batteries and battery states through different pulse signals so that the charger more correctly and more comprehensively identifies the battery embedded therein, the charger not only identifies the model of the battery, but also identifies the state information of the battery, thus, the charger automatically adjusts to adapt to the battery in the charging process, so as to prevent damage to the battery caused as the charging parameter and battery parameter are inconsistent in the charging process and prevent the battery from explosion.

Description

technical field [0001] The invention relates to an identification method between a charger and a rechargeable battery. Background technique [0002] The use of rechargeable batteries is currently a good choice to improve resource utilization and avoid environmental pollution from waste batteries. In various devices using rechargeable batteries, different types of battery packs may be used, and the electrical parameters of different types of battery packs are inconsistent. Need Chargers are treated differently. The current solution on the market is to add a distinguishing resistor to the battery pack to distinguish different types of battery packs with different resistance values. This method has a single function and cannot notify the charger of other information of the battery pack. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an identification method that can automatically identify the battery information ...
